PATENT oFFIon EINGE.

To all whom 'it may conccm:

Be it known that I, WILLIAM D. PAYN'rnR, a citizen of the United States,residng at Grass Valley, in the county of Nevada and State ofCalifornia, have invented certain new and useful Improvements in Hinges,ofv

which the followin is a specification. v

My invention re ates to the general class v of hinges and particularlyto that type commonly known as self-closing or risingl, hing'es havingfor their object the closin? of the swinging part by gravity, and theifting of said part in opening to clear any bottom obstructions, as, forexample, the clearin of a carpet or rug by a door.

he object of my invention is to provide a simple and eifective hinge ofthis nature 'which isl especially applicable to vertically hungstructures, particularly' doors and v gates, with the result that thedoor or gate y close by gravit or may be swung to an remain in a wi eopen position, or the hinflfe may be readily converted, when desire intoa common hinge.

To these ends my invention consists in the novel construction andcoaction of Ithe interengaging knuckles and the pintle of the hin e, allas I shall hereinafter fully descri e by reference to the accompanyingdrawings in which Figure 1 is a perspective view of one of the leaves ofmy hin'ge, showin ythe inclinedplane track of the lower knuc le. Fig. 2is`v a Perspective view of. the other leaf from the obverse face,showing1 the inclined-plane tongue of its knuckle. Fi 3 vis a perspec-.

tive view of the leaf of Fig. 2 from its'reverse face. Fig. 4 is a viewof the assembled hinge showing the tongue of one knuckle rlsing'on trackof the other. Fig. 5 is a view from the other side of the hinge showingthe tongue at rest on the level por- 'tion of the lower' knuckle beyondits inclined track. Fig. 6 is a perspective view of my hin e in a risinposition showing the incline track forme on a collar fast to the pintle,and showing the pintle locked against movement on its axis.

1 and 2 are the complelnental leaves of the hinge. The former is securedto the stationary part and the latter to the swinging wrt of thestructure to be hinged -t ether.

eakin in terms of doorhan 'ng, or example, t e leaf 1 is secured to t estile 3 of the door casin and the leaf 2 is secured to the door t, asindicated in Fig. 4.*

9, as in Fig.-1; and the knuckle 7 of the leaf 2 is complementally cutout to form an inclinedlane ton e 10, as seen in Figs. 2 and 3. herelatlve ositions of these mclined planes are suc that when the door isclosed and the two leaves lie in juxtaposition substantially parallelwith IAeach other, the tongue 10 of the knuckle 7 fits down upon thetrack 9 of the lower knuckle 6 and fills the s ace formed by the notchof which said 'track is one wall., v as the door is opened, the tongue10 travels uplon the inclined-track 9, as seen in Fig. 4, w loh has-theeffect of bodily lifting said door so that if the door be now released,it will, by avity, close again, as the ton e 10 travels own upon thetrack 9 to its mitial osition when the door is fully closed. his is theself-closing feature of the hinge. But, further, in order to provide fora termination of this self-closing action, so that if desired, the doorwhen more fully opened may be relieved of this closing action ofgravity, and remains open, it is to be noted that the inclined-planetrack 9 isnot carried in length to a oint at which the door is swungclear bac (at'which time the hinge leaves are alined as seen in Fig. 5)but stops short of this point, and the upper surface of the knuckle6,,as indicatedat 11 is level and horizontal. Therefore, when the dooris swung full back, the tongue 10 has assed beyond the inclined-planetrack 9 an now rests upon the level portion 11, as seen in Fig. 5, insufiiciently Stable uilibrium to remain there. In practice, it is st tomake the extremity of the tongue 10 somewhat fiat as shown at 10' sothat it'may find a more stable bearing on the level portion 11; and aswill be observed the beginnin of the inclined-track 9'is correspondmglyattened at 9', to receive the tongue extremity. It will thus be seenthat unless the door be swung to anapproximately full-back position, 1twill close by ravity, but, when the z full open position be esired, itwill remain But' open.L These conditions lprovide 'in general for allthe necessar 'usual requirements in the use of a door. naddition,however, to these conditions my invention contem lates 5 a third object,namely one in which the inge leaf 1, but are formed on or With aseparate collar 13 which ismade fast to and rotates with the intle 8. Asuitable looking device, 'such as the forkedl ke v14 in the head of thepintle is adapted to. ockI said pintle to the v 1 upper knuckle 5 of theleaf 2, so that it cannot turn on its -axis;.or torelease said intle inorder that it may freely turn. This key removably fits one of its legsdown into a hole in the head of thepintle, while its other legpasses-down in a key-way 15 in the periphery of the pintle head, andinto a keylVhen thus seate the pintle is locked to the leaf 1, andcannot turn on its axis, andwhen thus connected the collar 13 being faston' the pintle is also held against -movement and the ucklev 7 of theleaf 2l will act in conjunction therewith as. heretofore described,that,I isto say, the door can be made to close by gravity. or to remainwide open. But upon slipning the keyf14 up from its keyways 15 and16'and turning it on 'its' inner leg as an axis-and dro ping its outerVleg 'in a seat 17 in the pint e head, the pintle is freed from leaf-1-, and may turnon its axis. Then when the doorso ened the' intleitself will turn freely` and orm the' in ge axis, -w,hile by the weightof parts the knuckle 7 and the collar V13 remain relatively interlockedand one will not rise on the other.

The hinge' is thus an ordinary one, but ma'fy readily econverted backagain to a sel closing or ris' hinge, by resetting the key.
